In the early years, mathematics teaching focuses on the development of number and counting skills and concepts, primarily through the study of patterns and relationships. As the children progress through the school they will encounter experiences that will enable them to use and apply their mathematical knowledge to a variety of situations. The children will experience mathematics through direct practical activities, abstract forms, investigative, problem-solving work, as individuals, in groups or whole class.
